Parents should teach children about how to be a good member of the society, as half of the day children will stay with parents. It is their responsibility as well to correct their children and guide them in the correct way to become a responsible citizen. Whenever the children are going in a wrong direction, parents should notice it at earlier stages, so that they can correct it at the beginning stage itself instead of identifying at later stages. Unknown people/strangers friendship is the main reason to divert in a wrong guidance. Whenever they notice such kind of their kid's suspicious behaviour, they should advise their teachers to make sure that their children behave properly in the school and doesn't interact with the people who are responsible for spoiling their teenager's behaviour.
